Mercedes-maker Daimler AG’s plans for at least 10 purely battery-powered cars through 2022 will give the manufacturer the right lineup to meet stricter European emissions rules, Chief Executive Officer Ola Kallenius told reporters in Frankfurt. However, meeting the targets was a “substantial challenge” because consumer demand “can’t be mandated.”

The world’s bestselling luxury-car maker introduced the EQC electric sport utility vehicle last year, its first model to challenge U.S. electric-car market leader Tesla Inc. It followed up with a battery-powered version of the V-Class minivan this year and has shown a prototype EQA compact.

The S-Class, favored by wealthy managers and politicians the world over, has for decades delivered premium profits to Mercedes. The future for stellar returns on powerful and heavy sedans is darkening with the need to cut fleet emissions, with heavy fines looming in Europe.

Mercedes didn’t say when the car will be on sale, but outlined a real-world driving range of 700 kilometers (435 miles), and a battery that can charge to 80% in less than 20 minutes. The car also offers highly-automated driving on highways.

The interior features traditional and new materials, like white microfiber made from plastic bottles combined with maple. The roof material is a textile created with recycled ocean waste.

Daimler was one of the first manufacturers to warn of the growing headwinds triggered by the U.S.-Chinese trade spat. Homegrown problems have also beset the world’s biggest luxury carmaker, like production hiccups of the popular GLE SUV alongside growing regulatory scrutiny over its diesel emissions that have torpedoed the company’s earnings forecasts.
